TL494CN Overview
Capsuled in the 16-DIP (0.300, 7.62mm) package, the switching controller can be used for a wide range of applications. The dc motor controller is adquate to generate for 2 outputs. Tube is the solid enclosure in which PMIC is packaged. Transistor Driver dc switching's outputs (s) are supported. dc control's supply and operating voltages are 7V~40V. Qualified to work in an dc switcher with 0°C~70°C TA. There is a switch at 200kHz that can be used with this controller. As it has a Through Hole value, it can be used for general dc dc regulator. Dead Time Control, Frequency Control is used for efficient switching control in the dcdc regulator. A SWITCHING CONTROLLER analog integrated circuit is connected to the switch converters. Switching converters are designed with the terminal (s) at position DUAL . A variety of terminations with 16 of dc switching. This dc dc converter ic uses a variety of control techniques, including PULSE WIDTH MODULATION. DC switcher's voltage input is 15V. Other relevant dc to dc converter ics can be found by searching "TL494". 16 pins are present on switching converter. Switching converter is a type of Switching Regulator or Controllers in particular. It is recommended to use 7V as the minimum input voltage of dc dc voltage regulator. DC regulator outputs 40V voltage based on test statistics. The dc dc regulator's usual output current is 250mA, which should be noted down when you start a project. During power-up and power-down, the maximum duty cycle of the voltage regulator dc to dc is set to 48 %. DC switcher's Through Hole makes it qualified for most application and prototype designs. DC switcher'sSwitching controllers operate at 40kHz frequencies. It is suggested that users apply 15V to the voltage regulator dc to dc in order to run it safely and reliably in a circuit. SWITCHMODE? series dc to dc voltage regulator belong to this series.
